Answer:
<em>A) -3 + 9 + 4</em>
Step-by-step explanation:
We are given the following information: At 7:00 a.m., the temperature was -3°F. At 6:00 p.m., the temperature was 9°F greater than the temperature at 7:00 a.m. This means the temperature at 6:00 p.m. is calculated as -3 + 9.
We know this last temperature is 4°F less than the temperature at noon, thus the temperature at noon is calculated as -3 + 9 + 4
A) -3 + 9 + 4
Answer:So that's the change in Y. Now notice that X is increasing. By one unit each time. So we can calculate the slope. The slope is the change in Y divided by the change in X
Step-by-step explanation:
I'm sure there's an easier way of solving it than the way I did, but I'm not sure what it could be. Never dealt with a problem like this before.
Anyway, I just plugged in and tested. Chose random values for a, b, c, and d, which follow the rule 0 < a < b < c < d:
a = 1
b = 2
c = 3
d = 4


Simplify into standard form:



Use the quadratic formula to solve:

For functions in the form of

. So in this case:
a = 1
b = -4
c = 2
Plug them in:

Solve for 'x':




So the answer would be A.
Answer:
Step-by-step explanation:
(2,1), (-2,-1)
slope(m) = (-1-1) / (-2 - 2) = -2/-4 = 1/2
parallel lines will have the same slope
y = mx + b
slope(m) = 1/2
(-4,8)...x = -4 and y = 8
now sub and find b, the y int
8 = 1/2(-4) + b
8 = -2 + b
8 + 2 = b
10 = b
so ur equation is : y = 1/2x + 10 <==
